Portugal coach Fernando Santos had put off the decision for years, but eventually rolled the dice -- and benched Cristiano Ronaldo.
The gamble paid off handsomely as Goncalo Ramos struck a hat-trick in a 6-1 thrashing of Switzerland to set up a World Cup quarterfinal showdown with Morocco on Saturday.
Newly liberated Portugal has installed itself among the World Cup favorites and in an exhilarating 90 minutes blew away criticism of their "uninspiring" soccer.
The difficulty in Santos's decision stemmed from the circus around, and nourished by, Ronaldo, and the potential outcry, rather than a lack of alternatives or fear the team would struggle in his absence.
On the field, Portugal has plenty of impressive contenders for Ronaldo's throne, from Ramos, to AC Milan's Rafael Leao and Atletico Madrid's Joao Felix.
Santos, 68, has until now felt obliged to start Portugal's greatest ever player, a five-time Ballon d'Or winner and record men's international goalscorer.
The coach took over in September 2014 after a humiliating group stage elimination in Brazil, winning Euro 2016 before suffering a last-16 knock-out in Russia four years ago by Uruguay, which they beat in group play this time.
Ronaldo had started every World Cup game for Portugal since missing a group match against Mexico in 2006 before he was benched on Tuesday.
Even though in other matches without him Portugal demonstrated it can cope, or even thrive, it has been hard for Santos to abandon the 37-year-old. With Portugal already qualified for the knockouts, Ronaldo still started against South Korea in their final group match.
When he was substituted in the second half he showed frustration with his coach, who later spoke out against Ronaldo's behavior. Santos later insisted the decision to bench Ronaldo against the Swiss was for strategic rather than disciplinary reasons.
The reliance on Ronaldo -- or at least an unwillingness to be the man who ousted him -- has long starved Portugal of dynamism in attack, as all efforts go towards feeding him, and doing the defensive running that he cannot manage.
"That is what was intended, what we wanted," said Santos after the demolition of Switzerland. "We wanted a team that played with a lot of fluidity, we played very well."
It was a door to another world for Portugal, which won Euro 2016 through solidity and defensive grit rather than flair and creativity. It won just one game within the regulation 90 minutes in France.
For Santos to show openness to this kind of flexibility after eight years in charge was a surprise, and a welcome one for 70 percent of voters in a poll by Portuguese newspaper A Bola, who wanted him to drop Ronaldo.
Despite Portugal's thumping victory, Santos's decision inevitably carried fallout.
Portuguese newspaper Record reported that Ronaldo threatened to leave the World Cup squad, before changing his mind. That claim was denied by the Portuguese federation on Thursday.
Midfielder Otavio gave a press conference later that day in which he was repeatedly asked about Ronaldo, a common theme in Qatar after Ronaldo's bitter divorce from Manchester United dominated headlines for a fortnight.
Santos also maintained Diogo Dalot at right-back against Switzerland, and brought in Raphael Guerreiro at left-back, dropping Manchester City's Joao Cancelo.
Even though the defender is one of the best players in the Premier League, for Portugal he has struggled to hit the same heights. It was another move which paid off, as Guerreiro scored the fourth and set up Leao for the sixth in Portugal's demolition job.
By reaching the quarterfinals, Santos has enriched his legacy, guaranteeing at least Portugal's third best ever finish at a World Cup. He was already responsible for their only major trophy with the Euro 2016 triumph, as well as the 2019 Nations League win.
For years, he has brushed off criticism of Portugal's soccer as dull and uninspiring, preferring to focus on the results.
After showing more daring against Switzerland than at any other point of his extensive tenure, both in terms of his lineup and the performance, Santos may have found the right formula, at the right time.
